I'm using both side by side (D3s + D4). There my be a tiny difference in high ISO performance around 12,800, but it is minimal, and the D4 has a richer output....so, I still doubt your conclusions

Well Beavis you must have missed the picture I posted showing all three cameras side by side taken with my Sony A77.. Two days after they hit the market. Only the doubting Thomas then was a D800 lover... As I said before the D800 makes me thrilled I did not sell my D3x and tomorrow I am buying back my D3s and getting rid of my D4..As I said the better video capablilities of the D4 mean absolutely nothing to me, but the better still output from the D3s means a lot to me. I was also a big critic of Nikon sticking with 12 megapixels while everyone was increasing their sizes. Looks like Nikon knew what they were doing after all...All the more reason I anxiously await the Canon 1DX to see if they can do better..
